Genomes of animals as different as sponges and humans show conservation of global architecture. Here we show that multiple genomic features including transposon diversity, developmental gene repertoire, physical gene order, and intron-exon organization are shattered in the tunicate Oikopleura, belonging to the sister group of vertebrates and retaining chordate morphology. Ancestral architecture of animal genomes can be deeply modified and may therefore be largely nonadaptive. This rapidly evolving animal lineage thus offers unique perspectives on the level of genome plasticity. It also illuminates issues as fundamental as the mechanisms of intron gain.  相似文献

Efficacy of hexaflumuron against the fungus-growing termite Pseudacanthotermes spiniger (Sjöstedt) (isoptera,macrotermitinae)

The efficacy of hexaflumuron, a benzophenylurea insecticide, has been studied for the first time on a fungus-growing termite (Pseudacanthotermes spiniger Sjöstedt, Macrotermitinae). Results show that hexaflumuron could be useful in treating infestations of such pest species, which are of great economic importance in many tropical and equatorial countries. Foraging workers harvested and introduced treated food into the nest and subsequently contaminated the brood by trophallaxis. Hexaflumuron showed potent larvicidal activity. The compound did not appear to be rapidly degraded by the digestive enzymes of termite workers, nor by the symbiotic fungus Termitomyces eurhizus Heim growing on fungus combs. This chitin synthesis inhibitor did not act as a fungicide, since growth of the mycelium of this fungus was not inhibited in vitro. © 1998 Society of Chemical Industry  相似文献   

Possible human-avian transmission of Mycobacterium tuberculosis in a green-winged macaw (Ara chloroptera)     

Steinmetz HW  Rutz C  Hoop RK  Grest P  Bley CR  Hatt JM 《Avian diseases》2006,50(4):641-645

This report describes a case of Mycobacterium tuberculosis infection in a green-winged macaw (Ara chloroptera), confirmed by microbiologic and pathologic diagnostics, and notes a possible human-avian transmission. Clinical signs included cutaneous swellings, profound leukocytosis, and signs of osteomyelitis in the long bones. Proliferation consisted of several nodules with small greenish-caseous foci in cross-section and revealed a severe granulomatous inflammation with intralesional acid-fast rods. Mycobacterium tuberculosis was isolated from subcutaneous nodules and biochemically confirmed. The disease in avian species is of zoonotic importance.  相似文献

Morphological and morphometric features of knee joint in wild boar (Sus scrofa)     

İshak Doğan  Sevinç Ateş  Baran Erdem  Lutfi Takci 《Anatomia, histologia, embryologia》2021,50(6):1007-1014

In the study, it was aimed to reveal the structure of the knee joint anatomically and morphometrically in the wild pig known as the ancestor of the domestic pig. In the study, the left and right knee joints of mature 10 wild boars were used as material. For this purpose, the materials were fixed with 10% formaldehyde solution. Macroanatomical and morphometrical examinations of bones, menisci and ligaments involved in joint formation were performed after fixation. Trochlea and condyles of femur were examined, and various measurements were made. Trochlear labia were found to be the same size, and the condyles did not show a significant difference in size. The shape of lateral condyle of the tibia was trapezoid, and the shape of medial condyle was triangular. Moreover, the lateral intercondylar tubercule was higher according to the medial one. The presence of a shallow groove on the tibial tuberosity was detected. It was found that the width difference between apex and base was more pronounced on the anterior and lateral surface of the patella. Joint surface of the fibula was found to be flat in all materials. The menisci were ‘C’ shape, but the medial meniscus is more convex than the lateral one. It was observed that the outer edges were thick, while the inner edges were thin. Ligaments of the knee joint were well developed. When the findings of the study were compared with the literature, domestication seemed to have no significant effect in terms of the morphologic properties of the knee joint of wild boar.  相似文献

Prevalence of specific IgG-antibodies against Toxoplasma gondii in domestic turkeys determined by kinetic ELISA based on recombinant GRA7 and GRA8     

Koethe M  Pott S  Ludewig M  Bangoura B  Zöller B  Daugschies A  Tenter AM  Spekker K  Bittame A  Mercier C  Fehlhaber K  Straubinger RK 《Veterinary parasitology》2011,180(3-4):179-190

The protozoan parasite Toxoplasma (T.) gondii is one of the most common zoonotic infectious agents worldwide. Besides its sexual reproduction in cats, T. gondii can also infect a wide spectrum of other warm-blooded animals. These include animals used for human consumption such as pigs or chickens. Nevertheless, the role of turkeys for the epidemiology of T. gondii infections has not been studied thoroughly. We have established a kinetic ELISA (KELA) for the detection of T. gondii-specific IgG antibodies in turkey serum samples. The test is based on the recombinant dense granule antigens GRA7 and GRA8. These proteins were used as an antigen mixture at a concentration of 0.13 μg per well. The overall sensitivity of the assay was between 92.6% and 100% and the specificity ranged from 78.1% to 100%, depending on the method used to calculate these parameters. Using this KELA we examined 1913 turkey serum samples from 14 turkey farms from different areas of Germany. From these sera, 387 produced a signal in the KELA, corresponding to a true seroprevalence of up to 20.2%. The seropositivity rate in individual fattening cycles at individual farms ranged from 0.0% to 77.1%, whereas the rates were highly variable within the individual farms and individual fattening cycles. Consequently, conditions of animal husbandry could not be associated with particular seroprevalence rates. Although seropositivity cannot be linked directly to infectious tissue cysts in the muscle tissue of commercially produced turkey meat, we state that there is a potential risk of being infected by consuming turkey meat products that were not heat treated.  相似文献   

Gender, livestock assets, resource management, and food security: Lessons from the SR-CRSP     

Corinne Valdivia 《Agriculture and Human Values》2001,18(1):27-39

North Sumatra and West Java in Indonesia, the Andes of Bolivia and Peru, Western Province, the Coast and Machakos in Kenya, were Small Ruminant Collaborative Research Support Program (SR-CRSP) sites in which the role of small ruminants was studied and where technological interventions were designed. In all cases the target groups were poor rural households that could maintain sheep, goats, or South American camelids. The objective was to increase the welfare of families through the use of small ruminant technologies. Access to and control of resources, and intrahousehold dynamics were analyzed to understand if, how, and when, technological interventions help achieve this objective. The way in which the studied villages integrate into the market, the specific role that livestock and other productive enterprises play in the household economy, the risks faced by families in rural areas condition the role of livestock and other resource management technologies. As an asset, small and large stock are gendered, but this is qualified by the alternatives that household members have. Small ruminants under the domain of women, either through production or marketing, are shown to contribute to in-kind consumption or, as liquid assets, to household welfare purchases, in the case of Andean agropastoral households and households in Kenya. Women are also managers of the grazing areas, which are often fallow fields. The research experiences show the relationship between gender, resource management, and the ability to build livestock assets and security, in different houehold production systems.
